Lanxi Cement Plant | 0.7MW/1.505MWh liquid cooling energy storage system

Case introduction

• 

  Previously, the user-side energy storage project for a cement concrete products enterprise in Lanxi City, Zhejiang Province, constructed by Hua Power, was officially delivered and put into operation! The project has a total capacity of 0.7MW/1.505MWh and uses seven independently developed ‘100kW/215kWh integrated liquid cooling energy storage cabinets.’ Through intelligent energy storage solutions, it helps enterprises optimise their electricity costs and improve production efficiency, injecting new momentum into the green transformation of traditional manufacturing industries.

  Bid Farewell to "Off-Peak Production" and Unlock Production Capacity Potential

   

  As a typical energy-intensive enterprise, this client was previously restricted by the price difference between peak and off-peak electricity as well as grid load pressure, and thus adopted the "off-peak production" model for a long time: starting operations in the early morning and rushing production late at night. This approach not only prolonged workers' working hours and increased management costs, but also resulted in low equipment utilization and made it difficult to unlock production capacity.

   

  

  The implementation of Hua Power's user-side energy storage system has completely reversed this situation:

  
  

  • Peak Shaving and Valley Filling, Direct Electricity Cost Reduction: The energy storage system charges during off-peak hours at night and discharges during peak hours in the daytime, significantly reducing the proportion of the enterprise's electricity consumption at peak electricity prices and comprehensively cutting down electricity expenses.
  • 24-Hour Stable Power Supply: It smooths the production electricity load, avoids the risk of production shutdown caused by power grid fluctuations or power rationing, and ensures the all-weather efficient operation of the production line.
  • Flexible Production Scheduling, Doubled Efficiency: The enterprise no longer needs to "race against time" for production. Workers can operate during normal hours, reducing overtime costs. At the same time, the production plan is more scientific, and the equipment utilization rate has increased by more than 30%.

  The core equipment of the project adopts the 215kWh integrated liquid-cooled energy storage cabinet independently developed by Hua Power, achieving multiple breakthroughs through innovative technologies:

   

  • Efficient Temperature Control: Liquid cooling technology ensures the temperature difference of battery cells is ≤ 2℃, with the system cycle efficiency exceeding 87% and service life extended by 20%.
  • Ultimate Safety: Equipped with perfluorohexanone fire protection, and compliant with IP54 protection standards.
  • Intelligent Operation and Maintenance: The cloud-based Energy Management System (EMS) monitors charging and discharging strategies in real time, conducts remote fault diagnosis, and reduces operation and maintenance costs by 40%.

  Win-Win Economic and Social Benefits

  It is estimated that this project can bring the following benefits to the enterprise annually:

  • Save over 500,000 RMB in electricity costs, with a dynamic payback period of only 4-5 years.
  • Reduce carbon emissions by approximately 800 tons per year, contributing to the achievement of the "dual carbon" goals.
  • Increase production capacity utilization by 20% and significantly improve the working environment for workers.

   

  The person in charge of the client stated, "Since the energy storage system was put into use, production scheduling has become more flexible, and cost control has been more precise. We have truly achieved a double harvest of green benefits and economic benefits!"
